Abstracts |
Wheat cultivars Sakha 8, Sakha 61 and Sakha 69 were inoculated with vesicular arbuscular mycorrhiza (VAM; Glomus macrocarpum), and supplied with biofertilizer (Azotobacter, Azospirillum and Klebsiella) and/or 45 kg N/fed in a field experiment conducted in Egypt during 1996/97 and 1997/1998 to determine the effects of the treatment on the yield and yield components of the crop. Wheat cv. Sakha 69 gave the highest percentage of root infection with VAM; number of spikes/m2; number of kernels per spike; grain yield/ha; and protein, nitrogen and phosphorus contents during both seasons. Application of biofertilizer + 45 kg N/fed slightly reduced VAM infection ratios. Inoculation with VAM and application of the biofertilizer in combination with 45 kg N/fed increased the average grain yield/ha, and nitrogen and phosphorus contents of wheat cultivars by 16.14, 12.50 and 51.92%, respectively, during both seasons. Sakha 69 recorded the highest grain yield with the application of 45 kg N/fed + biofertilizer and VAM inoculation. |
